Proposed solution 3: Communities following communities

The ability for communities to "subscribe" to other communities is an idea that comes from this Github comment. This is, in my opinion, the best proposed solution by far. Community a can follow community b, making posts from b also appear on a.

What this means is that community moderators can choose to have posts from other communities to show up on theirs. That means if all the pancake communities are following each other, I can post on pancake@a.com and it would show up on the other pancake communities as well, and the comments would simply be grouped into just one post!

The main proposed solution doesn't force merging on anyone. Mods can decide whether or not they want content from other communities to show up in their space. No two news instances have to merge if they serve different audiences.

It isn't explicitly called out in the proposal but I could easily see there being an option for mods to unlink individual posts from other communities if they get too spicy.
